Description: Facets is designed to handle really tough applications of unidimensional Rasch measurement. It constructs measures from complex data involving heterogeneous combinations of examinees, items, tasks, judges along with further measurement and structural facets. It is designed to handle flexibly combinations of items of different formats in one analysis. Item types include dichotomies, rating scales with up to 255 categories, Poisson counts and Bernoulli trials. Multiple different measurement models can be included in the same analysis, including paired-comparisons, rank- order, rating scales, partial credit and dichotomizations involving from 1 to 255 facets.
